既要满足日益增长的粮食和能源需求，又要减缓气候变化，这一挑战推动了可再生技术和方法的开发和采用。农业光伏系统是一种允许在同一土地面积上进行农业和电力生产的方法。这些系统有可能减少对水的需求，提高某些作物的整体水分生产力。我们观察了在一个农业田的三个地点（对照、垄沟和面板下方）和两种不同灌溉处理（满灌和亏灌）下生长的番茄植株（Solanum lycopersicon var. Legend）的小气候和生长特征。对照全灌区a、b的作物总产量最高（88.42 kg/行，68.13 kg/行），随遮荫量的增加而降低，行全灌区a、b分别为53.59 kg/行，32.76 kg/行，面板全灌区a、b分别为33.61 kg/行，21.64 kg/行。行间亏缺处理的水分生产力比对照亏缺处理高53.98 kg/m(3)，比面板亏缺处理高24.21 kg/m(3)。这些结果表明，即使对于传统上被认为不耐阴的作物，农业光伏系统也有提高水分生产力的潜力。
The challenge of meeting growing food and energy demand while also mitigating climate change drives the development and adoption of renewable technologies ad approaches. Agrivoltaic systems are an approach that allows for both agricultural and electrical production on the same land area. These systems have the potential to reduced water demand and increase the overall water productivity of certain crops. We observed the microclimate and growth characteristics of Tomato plants (Solanum lycopersicon var. Legend) grown within three locations on an Agrivoltaic field (control, interrow, and below panels) and with two different irrigation treatments (full and deficit). Total crop yield was highest in the control fully irrigated areas a, b (88.42 kg/row, 68.13 kg/row), and decreased as shading increased, row full irrigated areas a, b had 53.59 kg/row, 32.76 kg/row, panel full irrigated areas a, b had (33.61 kg/row, 21.64 kg/row). Water productivity in the interrow deficit treatments was 53.98 kg/m(3) greater than the control deficit, and 24.21 kg/m(3) greater than the panel deficit, respectively. These results indicate the potential of Agrivoltaic systems to improve water productivity even for crops that are traditionally considered shade-intolerant.
